Two new stalked Crinoids from the Kei Islands. 
By 
Dr. Torsten Gisién. 
During a visit to the Zoological Museum of Copenhagen in 
December 1924 Dr. Mortensen exhibited to me the wonder- 
fully rich and beautiful collections of Echinoderms which he has 
brought together during his numerous journeys in foreign seas. 
Among other things he showed me also some Crinoids from his 
last expedition, brought home from the Kei Islands. Two of the 
stalked Crinoids at once struck me as new, and Dr. Mortensen im- 
mediately offered me to study and describe them, an offer which I 
was delighted to accept, and for which I beg here to express my 
best thanks. I am also indebted to him for the 3 photos, Figs. 22, 
1—3, which he has kindly presented to me. 
As I shall show below one of these Crinoids was still more 
interesting than I suspected at a first glance. I have therefore 
been forced to create a new genus for this singular type. But the 
second Crinoid also presents several curious features, giving it a 
very characteristic appearance, distinet from all other species of 
Democrinus in which genus I have ranged the new species.

Stem with about 86 segments, the 30 most distal being covered 
by a characteristic calcareous granulation by which the articulations 
get somewhat obscured. Total length of the stem 255 mm. The 
9 most proximal segments very short and discoidal, from the lOth 
inereasing in length, the 15th about squarish. Longest segments 
L=1V4 — 2Xbr. About 10 of the most proximal columnals evid¬ 
ently connected by a close synostosis, slowly transforming into a
